Lessee...
I've been in my house about 3 1/2 years now. Here's a quick, off-the-top-of-my-head, rundown of the expenses I've incurred...
$50: materials to re-stain hardwood floor in one of the bedrooms
$50: materials to fix a broken window (window pain, the little metal triangles that hold it in, window putty, wire for the pulleys, etc
$20: parts to replace the innards of the toilet
~$250: call to have the plumber come out and replace the sink drainpipe
~$250: call to have the plumber come out and fix a leaky pipe to the water heater
$5.00: roofing tar to fix a rotten, leaky spot in the roof. I was able to scrounge around and find everything else I needed: shingles, plywood, nails, flashing, etc, so I only had to buy the tar.
~$500: materials to replace about 56 feet of stockade fence. I put it up myself. Included 4x4 posts, 6x8 fence sections, heavy-duty screws, and 2x10 boards across the bottom to make the fence taller
~$90: 3 cubic yards of topsoil, delivered by myself, using my pickup truck (3 separate trips)
$240: new exhaust system, when said topsoil caused truck body to sag far enough to pinch the exhaust system between the bed and rear axle, causing it to break. First, the tailpipes fell off. Then the muffler. It was rusty anyway, but those topsoil loads definitely sped up the replacement. A cubic yard of topsoil weighs about 2700-2800 pounds. There's a sticker in the truck's glovebox that says "bed capacity: 864 pounds". Note to self: don't do that again!
$50: had to have an electrician I knew come out and replace a breaker in the circuit box
$28,000: new 24x40 4 car garage, plus roughly 200 feet of gravel driveway, plus running wiring roughly 150-175 feet from the house to the garage, underground.
I'm sure that I've missed a few minor things here and there, so figure maybe $31000 tops. For 3 1/2 years. So yeah, once you include that big garage I had built, I'm coming in at around $8850 per year!
